In relation to the load factor, the specified load can be expressed in terms of which forces?

• A. Aerodynamic forces
• B. Inertia forces
• C. Ground or water reactions
• D. All of the above

Answer: (D)

Load factor looks at how much load the airframe must carry relative to its weight, and that load comes from several sources. Aerodynamic forces, especially lift, directly contribute to the load on the wings and structure. Inertia forces arise from the aircraft’s accelerations—during turns or maneuvers, the mass experiences forces that add to the overall load. Ground or water reactions come into play when the airplane is in contact with a surface, such as landing, where the surface provides normal forces that increase the load on the airframe. Since the specified load is a combination of these effects, it can be expressed in terms of aerodynamic forces, inertia forces, and ground or water reactions.
